We declare that all the original material in each publication of this book is in the public domain. This includes not only previously unpublished manuscripts but also compilations of previously unconnected information.
"Public Domain" means you may freely use it as you wish; hopefully you will give proper attribution for your source. However, you must not attempt to copyright my public domain material for your own benefit. (One person incorporated my material into her 1993 book and applied for a copyright; then she audaciously threatened me for continuing to publish my 1975 public domain work!)
We acknowledge the claims of legitimate copyright holders to control their material. If any such feel that we have overstepped the bounds of fair usage, we will remove that material. For example, biographical information on the earlier Blackwell generations has been withdrawn at the request of a copyright holder. Each biographical sketch contains a full list of references so that the source of all the information is clearly given.
We welcome additions and corrections. Sharing information is one purpose of this book. However, please do not send us information copyrighted by others. A photocopy of the full title page and a brief note as to the information contained would be much appreciated. Then we can consult the original work.
Also please do not send us information which you intend to later claim copyright over without clearly marking it as such. Since we operate upon the principle of publishing into the public domain (and have done so perennially for over two decades), we assume any unmarked information sent to us is free for publication into the public domain.
[P.S. -- The public domain status applies to JNC's original text and its conversion to HTML form (and also to the GEDCOM file I have created from the data collected by him), but not necessarily to the images I have created or scanned in.
